I don’t own a ton of rewards cards so I’m not sure I’m the prime target for this app, but for those of you with countless rewards cards and point cards, Wallaby is the app you want to download.

The app tracks your rewards cards (it doesn’t access any of the card’s personal info, so don’t worry) and it actually tells you which card to use to gain the most amount of rewards points for that location. Eating at a restaurant? Use this card. Buying an airline ticket? Use that card. Getting some museum tickets? Use this card for discounts and points. It’s all so simple and really, really clever use of location info via the iPhone.
